[time-nuts] Power supply help

[Stan W1LE]

Hello Joe,

Put a bid price on it that reflects the associated risk.
Or delay the purchase till you can test it with a load.

I suspect that if it powers up, it would probably work in your application.

I have a few bench type HP power supplies and they are all nice and RF 
quiet,
but are rated well below the 40A you are considering.

A good test would be to load it down to its rated current and voltage
and monitor noise with a clamp on current probe ( on one lead)
to a low frequency spectrum analyzer

No info in the '82, '89, or '93 HP Test and Measurement catalog

It may not be a HP manufactured product, but rather another manufacturer 
made it for HP,
and HP slapped their label on it.

Open it up and look for tell tale signs of the original equipment 
manufacturer, possibly on the PCB.

I have a 51V, 57A switch mode PS with a HP label on it, a computer 
server PS, but it was made by Astec
and their website showed the same ASTEC model and detailed application info.
